MACHINE-VISE.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application flied April '7. 1903. Renewed October 17,1906. Serial No. 339,394.

T0 (11M Lul/1,0m, t may concern:

Be it known that'I, HENRY F. KELLEMEN, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Machine-Vises; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the sanie,'reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form part of this specification. l

The object of my invention is to provide a machine-vise having certain features and adjustments whereby its utility and the utility of the machine on which it is employed are greatly increased.

The machine-vises of the class to which this invention relates are more particularly intended for us'e in or with milling-machines. In such machines cutters are mounted on an arbor above a movable and vertically-adjustable table. In order to obtain the maximum or even a large amount of work from a single machine, it is necessary or desirable to provide two or more cutters on the same arbor adapted to simultaneously operate on two or more pieces secured on the table or bed. The machine-vise is secured on the table to hold the piece or pieces to be operated upon by the cutters. The cutters are subject to wear, and in sharpening or grinding their diameters become reduced. When a single cutter is used on the arbor, this reduction in size is compensated for by adjusting up the table. When two or more cutters for operating on two or more pieces are employed, they wear down and are reduced in size in sharpening unequally. Hence a single adjustment in the table is inadequate to produce exact and accurate work from a series of cutters operating simultaneously.

The object of this invention is, among others, to provide a machine-vise which overcomes the above-lnentioned defects and'furnishes a vise for multiple work on the same machine bed or table.

In the drawings, Figure 1 shows a perspective view of a machine-vise embodying the features of my construction. Fig. 2 shows a plan view of the same. Fig. 3 is a side elevation. Fig. 4 is a longitudinal section on line A B of Fig. 2. Fig. 5 is a cross-section on line O D of Fig. 4, showing the parts to the left in elevation. Fig. 6 is a cross-section on the same line, showing the parts to the right in elevation. Fig. 7 shows a similar section to Fig. 6 of a slightly-modified form of construction. Fig. 8 shows a similar section to Fig. 6 of still another modified form of construction.

Referring to the reference-figures in a more particular description, 1 indicates the visebase, which is adapted to be secured on the bed or table of the machine.

2 is a stationaryjaw-block secured to the base 1 and', as the construction is shown, has openings through which pass the slides or bars 3. The bar 3 on the under side rests directly on the base-plate 1 and carries at one end the movable aw 4, which is preferably secured thereon by screw, as shown. At the other end the slide or bar 3 carries the operating-lever 5. The lever 5 is mounted on a pivot 6 in the bifurcated end of the bar 3 by means of the eccentric pieces 7, which are clamped between the clamp part 3a and the end ofthe bar 3.

The short end of the cam-lever 5 operatesA against a shoulder part 2a of the block 2, which extends down between the bifurcated parts of the slide 3. The cam end of the lever is also adapted to engage with a projection or lever-stop 18 on the base, and thereby operate to throw the jaws into open position. The block 2 provides a mounting for the adjustable jaw face-piece 8. In the construction, as shown, a single jaw-piece is provided for the block 2, which is common to the two movable jaws 4 4; but it is also obvious that two separate j aw-pieces in lieu of 8 may be provided. (See Fig. 8.) The jaw face-piece 8 is secured to the block 2 by means of screws or bolts 9, extending laterally through the block.

In the construction as shown in Fi s. 1 and 2 two of the bolts 9 are shown, whi e in the construction as shown in Fig. `7 a single bolt in this position is shown. The lower edge of the face-piece 3 is received in a rabbeted edge of the block 2, and under its ends there are provided adjusting-screws 10, which are accessible for the purpose of accomplishing the adjustment. On the movable jaws 4 there are provided adjustable face or holding pieces 11. These are received in a rabbeted edge on the face of the jaw and are held to loe the jaw by means of a bolt 12. These faces 1.1 are adjustable toward and from the base of the vise by means of the adjusting-screws 13 13, arranged under each end of the facingpiece, preferably in recesses therein, and in position so that they are readily accessible for adjustment'. In practice the stationary jaw, and in some instances the movable jaw, will have the facing-pieces formed more or less to the form of the piece to be held bythe vise and operated upon by the machine. In the case of a aw 3, common to two or more movable jaws, it would have such recesses or forms in positions opposite the faces of the movable jaw. Secured on the slides 3 adjacent to the movable jaws there are provided plates 14, adapted to close a recess below them and prevent chips and foreign matter coming into the space and blocking the operation of the vise.

The vise shown in the drawings is a double vise-that is to say, having two independently-operating holding-jaws adapted to hold two pieces of work. The double form, how* ever, is not necessary, as two or more single forms of vise might be secured on the bed of the milling-machine, as hereinbefore suggested, and substantially amount to the double form of vise shown. With this form of vise any variations in the sizes of the cutters from wear which cannot be takenA up by the adjustment of the table, as hereinbefore suggested, can be taken up or provided. for by adjusting the jaw-faces by means of the screws 10 and 13. The adjustments at this point are ordinarily very small, being in the hundredths and thousandths of an inch ordinarily, but notwithstanding an all-important point in -line work on milling-machines.

The operation of the device further than the points of adjustment are too obvious to warrant their being set forth in this speciiication. It may be noted, however, in this connection that a number of facing-pieces for the same vise can be provided having forms adapted to different work, if desired, and be made interchangeable in the same vise, sol that only the facings of the'jaws need to be changed in making a change of the work on which the machine is running.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination in a machine-vise of a base, a fixed jaw-block and Xed lever-stops on the base, two sliding bars passing through the block, movable jaws carried by said sliding bars respectively, operating and locking levers pivoted on the opposite ends from the jaws of the sliding bars respectively, the short arm ot said lever arranged to engage between the pivot and Xed jaw-blocl to lock the movable jaw in closed position, and engage with the lever-stop for opening the jaw, and means for adjusting the position of the leverpivots in the slide-bars, substantially as set forth.

2. The combination in a machine-viseot1 the character described, of a base having the centrally-located fixed jaw-block 2 thereon, with. the independently adjustable facepiece 8 mounted on and securedv to the jawblock for vertical adjustment, means 10, for producing said vertical adjustment, movable jaws 4 mounted on horizontal draw-slides passing through the jaw-block 2, verticallyadjustable face-pieces 1.1 for the jaws 4 respectively, and means 13, for producing said adjustment, and manual means for opening an d closing the jaws with reference to the jawblock provided on the opposite side of the jaw-block from the jaws, substantially as set forth.

In witness whereof l have a'l'liXed my sig nature, in presence of two witnesses, this 2d day of April, 1903.
